Abstract

A sharp feature is observed at about 600 MHz in the inelastic scattered light spectrum of fibers of calf thymus DNA. It broadens so as to be no longer distinctly resolved when the ordering of a fiber is disrupted by convection caused by laser heating. To within experimental uncertainties the frequency of this feature is wavevector independent. A possible origin of the feature lies in a defect resonance such as that associated with the chain terminus.
